Remember when Coldplay’s Chris Martin announced he would help curate the Global Citizen festival lineup for 15 years to come? Well, Global Citizen has announced the headliner roster for Martin’s first event, Global Citizen 2015 Earth Day. The free concert – which will take place at the National Mall in Washington D.C. on April 18 – will feature My Morning Jacket, No Doubt, Fall Out Boy, Usher, Mary J. Blige and Train.

The event -- which is organized by the Global Poverty Project and Earth Day Network -- strives to raise awareness and advocacy to combat climate change and extreme poverty.

“Global Citizen 2015 Earth Day will be a moment for every one of us to call for serious action to end extreme poverty and solve climate change,” Global Citizen festival founder Hugh Evans told Rolling Stone. “Our goal with the event is to see major commitments from the World Bank, United States, South Korea, Canada, Ireland, France, Denmark and more to ensure that access to food, education and sanitation is available to all.”

The Global Citizen festival – which Martin will also help curate – takes place the four days leading up to Earth Day on April 22.

Earth Day headliners Fall Out Boy said they are “honored and humbled” to join the event.

“Taking direct action to make the world a better place – to eradicate extreme poverty and find a solution for climate change – is essential not only for us but our kids and all future generations,” the band said in a statement. “If our participation and music can bring attention to these issues then we’re doing our job right. We must stand together to make lasting change.”
